The phenomenon where higher expectations lead to an increase in performance—a specific type of expectation effect named after Rosenthal's famous experiment in education.
The tendency to respond to questions in a manner that will be viewed favorably by others, over-reporting "good" behavior and under-reporting "bad" behavior in self-reports.

The tendency to present oneself in a favorable light, managing impressions to create desired social images—affecting both what we say and how we perceive ourselves.
The tendency to make internal attributions for in-group successes and external attributions for in-group failures, while doing the opposite for out-groups.
The perception that members of out-groups are more similar to each other than are members of one's own group—"they" are all alike while "we" are diverse.
In some contexts, the opposite of outgroup homogeneity—perceiving one's in-group as more similar than out-groups, especially for groups that are small, distinctive, or identity-central.
